User Manual

IV-3-1-2 Advanced

These settings are for experienced users only. Please do not change any of the

values on this page unless you are already familiar with these functions.

Changing these settings can adversely affect the performance of your

access point.

Contention

Slot

Select “Short” or “Long” – this value is used for contention

windows in WMM (see IV-3-6 WMM).

Preamble

Type

Set the wireless radio preamble type. The preamble type in

802.11 based wireless communications defines the length of the

CRC (Cyclic Redundancy Check) block for communication

between the access point and roaming wireless adapters. The

default value is “Short Preamble”.

Guard

Interval

Set the guard interval. A shorter interval can improve

performance.

802.11g

Protection

Enable/disable 802.11g protection, which increases reliability

but reduces bandwidth (clients will send Request to Send (RTS)

to access point, and access point will broadcast Clear to Send

(CTS), before a packet is sent from client).
